I know in another of your requests, that you mentioned your dad has gone to a Divorce support group, church, etc. I'm the one with a son that is your age. Go buy the book, The Power of a Praying Husband, for your dad...or have him go and get it. I bought The Power of a Praying Wife and love it.

Lord, please help us all, the angry, hurt spouses that are being led away by evil, and also the spouses that have been left behind, standing in the gap (or attempting to) for their marriage. Please shield us from the lies of the enemy, and to have hearts filled with the truth. Guide us to you and back to our marriages. Help us to be completely forgiving of each other, and to be humble enough to ask for forgiveness when we need to. Please keep us from negative emotions. Soften our hearts towards one another. Give us hearts strong in faith, so that we don't have to be afraid of the future. Protect the children that are caught in these stormy times. Lead them to desire and encourage the restoration of their parent's marriage, and open the parent's ears so that they will hear it.
Amen
